34 hornblende family. the Saualp in Carinthia, with quartz, calcareous-spar, garnet, and common actynolite; in the Zillcrthal in the Tyrol, with quartz and hornblende; and imbedded in whitestone at Waldenberg, in the Saxon Erzgebirge; also in France, Transylvania, Hungary, and Spain. Asia.—In the Uralian Mountains ; also in India. America.—Near Baltimore; and at Maniquarez in South America. Uses. In India it is cut and polished, and sold as an inferior kind of sapphire. Observations. 1. It is distinguished from Aclynyliteby its cleavage, and its infusibility; from blue coloured Quartz, and Sapphire, by its inferior hardness; from Mica by its superior hard ness, its infusibility, and its being common flexible, where as mica is elastic-flexible: from Tremolite, by colour, figure, and infusibility. 2. It was first described as a kind of schorl, under the names violet schorl, blue schorl-spar, pseudo-schorl; after wards as belonging to the mica or talc species, under the names blue mica and blue talc. Some observers arranged it with felspar, and named it sky e-blue foliated felspar , and by others it was denominated foliated beryl. It was Werner who first correctly pointed out its characters. Al though it appears to be allied to talc, actynolite, and tre- molite, yet the affinity is so distant, that at present it stands almost isolated in the system. If increasing the number of divisions in the system were not an evil, it might be an improvement to place it as a member of a distinct family, which would be named the Kyanite Fa-
